NGK 6510 LTR7IX-11 Iridium IX Spark Plug (4 Pack)

Have used these since I purchased my Focus ST and Ecoboost Mustang. I have ran them since stock and tuned. I change spark plugs every 10 k miles. My Focus is big turbo pushing 25 psi on e30 and does not misfire during wot pulls at all. Mustang is stock turbo e30 and no misfires during pulls as well.

As described. They came with a .038 gapped. Had to adjust a little bit

Great Price For The 6510s

Mazda 6 2.3 fit nice, reemplazo de sp548x

Never had one go bad, or foul. I've used this brand in a tuned Focus ST and stock Toyota 86.

They do what they do, just a better price at almost half than the auto parts store

Rule of thumb for tuned cars is to replace spark plugs more frequently than stock. So, I usually change my spark plugs every 3rd or 4th oil change with these. They’re not pre-gapped so you’d have to ask your tuner for that specification and gap them yourself which isn’t difficult. And, they’re also cheaper to get on Amazon even if you have to wait a couple of days. These plugs need a 5/8 spark plug socket. They don’t require anti-seize. And, the torque spec is 106 in/lbs for the Focus ST. If you don’t have a torque wrench, once you get the spark plug snug, you just turn it 1/8 more and you’re good. There’s instructions on the website if you need it. So, if you’re looking for colder plugs for your tuned Focus ST then look no further. You can also purchase the Denso two step colder plugs but that’s if you’re pushing high whp.

Terrible plugs. Started to misfire within tbe first month. Put the old plugs back in and the vehicle ran great. Wow what a colossal waste of money.

Desastroso. Son bujías que aparecen como compatibles con mi vehículo. Se han instalado a su par de apriete hace menos de 2.000 kms y siguiendo todos los cuidados necesarios para su correcta instalación. Han resultado nefastas, una de ellas presenta fugas por la cerámica, venían con diferentes distancias de electrodos y lo peor es que han ocasionado la avería asegurada en una de las bobinas (no tengo claro que hayan podido ocasionar daños en las otras 3 bobinas). Todo ello obliga, al necesario cambio de todas las bobinas y de nuevas bujías. Conociendo la marca NGK, dudo mucho que sean originales.

Le quedó perfectamente bien en mi Subaru forester y funciona correctamente.

Muy buena calidad, y vienen las 4 en perfecto estado, las recomiendo!

Se las puse a mi focus st 2014 y le quedan perfecto ya que necesitaba una bujias más fuertes. Gracias

Envío bastante rápido, producto 100% original lo volveré a comprar cuando sea necesario
